An endoscope system includes an image acquisition section, an attention area setting section, and a dimming control section. The image acquisition section acquires a captured image that includes an object image. The attention area setting section sets an attention area within the captured image based on information from the endoscope system. The dimming control section performs a dimming control process that controls the intensity of illumination light based on the attention area set by the attention area setting section.

First RGB image signals are inputted. A first B/G ratio and a first G/R ratio are calculated. The first B/G ratio and the first G/R ratio are converted into a second B/G ratio and a second G/R ratio, respectively, through a color information conversion process. Owing to the color information conversion process, a difference between first and second observation areas in a second signal ratio space formed by the second B/G ratio and the second G/R ratio is greater than a difference between the first and second observation areas in a first signal ratio space formed by the first B/G ratio and the first G/R ratio, and a difference between the first and third observation areas in the second signal ratio space is greater than a difference between the first and third observation areas in the first signal ratio space.

A flexible endoscope insertion method includes: rotating a hollow organ by changing the body position to semilateral position or lateral position for observing the lateral wall of the lumen; turning the tip of the flexible endoscope to the lateral wall of the lumen by rotating the endoscope in the counter direction of the lumen; and retracting the organ with the endoscope itself by rotating the endoscope in the counter direction of the lumen. In other embodiments, the method includes: rotating a body cavity by changing the body position to the appropriate position for observing the lateral side of the organ; turning the tip of the flexible endoscope to the lateral side of the organ by rotating the endoscope in the direction of the lateral side of the organ; and retracting the organ with the endoscope itself by rotating the endoscope in the direction of the lateral side of the organ.

Devices and methods of endolumenal formation of gastric sleeves are described. Some embodiments allow templating of a gastric sleeve by a gastric bougie, exposing a selected amount of tissue for suturing access, while maintaining sufficient internal working space for suturing within the template lumen.

A medical device comprising an endoscope accessory for attachment to the working end of an endoscope. The coupler device provides a flexible working channel extension from the endoscope so that instruments can exit the endoscope at various angles. The device also provides a protective cover to reduce the ingress of debris, fluid, bacteria, or other unwanted matter from the working end of the endoscope which could lead to infection.

The invention relates a method (100) and a device (200) for analyzing a video sequence captured by Small Bowel (SB) Capsule Endoscopy (CE) devices, when placed in a patient's body during a SBCE video examination, the clinical setting of the patient being chosen from overt Obscure GastroIntestinal Bleeding (OGIB), occult OGIB, or suspected Crohn's Diseases (CD), by calculating a level of “clinical relevance” of the findings detected by the SBCE devices according to the chosen clinical setting, comprising: (a) collecting (110), by a memory, at least one video sequence captured during a SBCE video examination; (b) automatically detecting (120), by a processor, from the video sequence, at least one image comprising at least one abnormal finding in the Small Bowel detected among sixteen types of SB findings; (c) counting (130), by the processor, the abnormal detected findings; (d) classifying (140), by the processor the abnormal detected findings according to predetermined rules; and (e) outputting (150), by a display, the “clinical relevance” of each abnormal detected finding.

An upper gastrointestinal bleeding monitoring system includes a detection device and a signal processing device to determine bleeding condition of an upper gastrointestinal tract by using relation of time and intensity ratios of RGB three primary colors. The detecting device is placed to the upper gastrointestinal tract of a patient via his/her mouth or nasal passage and then stay the upper gastrointestinal tract for several days for detection of bleeding. The signal processing device may receive and display signal from the detection device to help medical professionals check if bleeding occurs in an upper gastrointestinal tract. Moreover, a procedure of determination of bleeding in an upper gastrointestinal tract with the upper gastrointestinal bleeding monitoring system is described.

An integrated medical bite block is engaged by a user's teeth and installed into the user's mouth. The bite block includes a through passageway, an upper grove, and a lower grove. The through passageway is penetrating through the bite block. One end of the through passageway comprises an inlet opening, the other end comprises an oral opening. The oral opening is connected with the user's mouth. An upper surface of the bite block provides the upper grove configured for receiving one or more upper teeth (maxillary teeth) of the user, and a lower surface of the bite block provides a lower grove configured for receiving one or more lower teeth (mandibular teeth) of the user. One distance between the lower grove and the oral opening is greater than the other distance between the upper grove and the oral opening, thereby the invention serves to extend forward the mandible and reposition a malposition between the mandible and the maxilla of the user.
